Iceland knows how to stop teen substance abuse

Today, Iceland tops the European table for the cleanest-living teens. The percentage of 15- and 16-year-olds who had been drunk in the previous month plummeted from 42 per cent in 1998 to 5 per cent in 2016. The percentage who have ever used cannabis is down from 17 per cent to 7 per cent. Those smoking cigarettes every day fell from 23 per cent to just 3 per cent.

The way the country has achieved this turnaround has been both radical and evidence-based, but it has relied a lot on what might be termed enforced common sense. “This is the most remarkably intense and profound study of stress in the lives of teenagers that I have ever seen,” says Milkman. “I’m just so impressed by how well it is working.”

This idea spawned another: “Why not orchestrate a social movement around natural highs: around people getting high on their own brain chemistry – because it seems obvious to me that people want to change their consciousness – without the deleterious effects of drugs?”

“We didn’t say to them, you’re coming in for treatment. We said, we’ll teach you anything you want to learn: music, dance, hip hop, art, martial arts.” The idea was that these different classes could provide a variety of alterations in the kids’ brain chemistry, and give them what they needed to cope better with life: some might crave an experience that could help reduce anxiety, others may be after a rush.

The results of these surveys were alarming. Nationally, almost 25 per cent were smoking every day, over 40 per cent had got drunk in the past month. But when the team drilled right down into the data, they could identify precisely which schools had the worst problems – and which had the least. Their analysis revealed clear differences between the lives of kids who took up drinking, smoking and other drugs, and those who didn’t. A few factors emerged as strongly protective: participation in organised activities – especially sport – three or four times a week, total time spent with parents during the week, feeling cared about at school, and not being outdoors in the late evenings
